“Didymo” Is In Connecticut Waters
Forwarded from the CT Council of Trout Unlimited
The invasive freshwater alga, Didymo - commonly called "Rock Snot" - has been discovered in the West Branch of the Farmington River. The first reported case in Connecticut.
With Opening Day just two weeks away, there is a very real danger of didymo spreading to other streams in the state. Please read the following and help us prevent didymo from spreading to other rivers and streams.
Why It Is A Threat
Didymo - Didymosphenia geminata - is a highly invasive alga species that was first identified in New England in 2007. During blooms, didymo can form thick mats of material that feel like wet wool and are typically gray, white and/or brown, but never green in color. These mats form on the bottoms of rivers and streams and can potentially smother aquatic plants, aquatic insects and mollusks, impact fish habitat and alter aquatic food chains.
What You Can Do
According to the Connecticut DEP, humans are primarily responsible for the recent spread of didymo. Anglers, kayakers and other water sport enthusiasts can all unknowingly spread didymo. The microscopic cells can cling to many surfaces on fishing gear, including wader seams, boot laces, gravel guards, wading boots (especially felt soles), boats and other surfaces and remain viable for months under even slightly moist conditions. To prevent the spread of didymo, the DEP is asking anglers to practice CHECK, CLEAN, DRY procedures.
CHECK
Before leaving a river, stream or lake, remove all obvious clumps of algae and plant material from fishing gear, waders, clothing & footwear, canoes & kayaks, and anything else that has been in the water and place these clumps of algae in the nearest trash container. Leave them at the site. If you find any later, clean your gear and dispose of all material in the trash.
CLEAN
Soak/spray & scrub boats and all other "hard" items for at least one minute in either very hot (140°F) water, a 2% bleach solution, or a 5% dishwashing detergent solution. Absorbent materials such as clothes and felt soles on waders should be soaked for at least 40 minutes in very hot water (140°F), or 30 minutes in hot water (115°F) with 5% dishwashing detergent. Freezing thoroughly will also kill didymo.
DRY
If cleaning is not practical, after the item is completely dry to touch, wait an additional 48 hours before contact or use in any other waterway.
What Trout Unlimited Is Doing
Trout Unlimited leaders from across the state are working closely with the Connecticut DEP, angling groups, watershed associations and others to develop a long-range plan for addressing the threat posed by didymo.
In the coming weeks, we hope to have more practical advice on how you can help us contain the risk of didymo.
In the immediate term, our efforts will be on raising awareness of the issue and helping anglers and other recreational river users learn how they can help fight the spread of didymo.
Help us spread the word. Forward this email to your friends, fellow fishermen and others who may come in contact with didymo in the West Branch of the Farmington River.
Thank you for all that you do for coldwater conservation here in Connecticut.
Timely Info on Cleaning your Waders
From the Fish and Wildlife Service and Others
Trout Unlimited has asked manufacturers to discontinue manufacture of felt-soled wading boots in 2011 due to the danger of spreading aquatic nuisance species in our streams. Here is a link to TU"s press release on the subject.
Dave Langer from Cabelas in East Hartford provided two links to information on how to clean your felt-soled waders and other equipment to help solve the same problem. Since many of us will be heading to the steams soon in our felt-soled boots, this information is very timely.
The first link is to www.protectyourwaters.net/ This link is sponsored by the USFWS and the U.S. Coast Guard.
The second link is to www.cleaninspectdry.com/default.asp This is a website sponsored by the Greater Yellowstone Area Working Group.
Air Exposure and Fish Survival
More than 60 seconds is too long
In-Fisherman magazine, April-May 2007, reports on the work of J.F. Schreer, D.M. Resch,
M.L. Gately, and S.J. Cooke regarding brook trout survival in air. These biologists tested hatchery
brook trout acclimated to 50 deg F water. They chased the fish for 30 seconds to simulate angling, then
held them in the air for periods from 0 to 120 seconds and measured their subsequent swimming
performance. Exposures up to 60 seconds had little effect but an exposure of 120 seconds reduced
swimming ability by more than 75%. Nearly half the trout held out this long were unwilling or unable
to swim at all until they recovered sufficiently.
The trout were observed for 3 months after the tests and there were no deaths so the longer exposure
wasn't fatal. However, the researchers recommend that air exposure should be limited to 60 seconds or
less.
